The $1.90/day (2011 PPP) line is not an adequate or in any way satisfactory level of consumption; it is explicitly an extreme measure. Some analysts suggest that around $7.40/day is the minimum necessary to achieve good nutrition and normal life expectancy, while others propose we use the US poverty line, which is $15. https://www.cgdev.org/blog/12-things-we-can-agree-about-global-poverty
The real (inflation-adjusted) incomes of the poorest half of the Chinese population increased by more than four hundred percent from 1978 to 2015, while real incomes of the poorest half of the US population actually declined during the same time period. https://www.nber.org/system/files/working_papers/w23119/w23119.pdf
By the end of 2020, extreme poverty, defined as living on under a threshold of around $2 per day, had been eliminated in China. According to the World Bank, the Chinese government had spent $700 billion on poverty alleviation since 2014. https://www.nytimes.com/2020/12/31/world/asia/china-poverty-xi-jinping.html
Interesting theory. Let’s see how it stands up in face of actual facts of the situation…
Household savings hit major highs across China https://www.chinadailyhk.com/hk/article/315229

From 1978 to 2000, the number of people in China living on under $1/day fell by 300 million, reversing a global trend of rising poverty that had lasted half a century (i.e. if China were excluded, the world’s total poverty population would have risen) https://www.semanticscholar.org/paper/China’s-Economic-Growth-and-Poverty-Reduction-Angang-Linlin/c883fc7496aa1b920b05dc2546b880f54b9c77a4
